Embodiment Construction

[0024] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0025] The heat storage heat preservation water storage device of this kind of solar water heater comprises cylinder body, and the phase change energy storage material is placed in the heat storage heat preservation layer of cylinder body, when the water storage device absorbs heat, the phase change energy storage material changes from solid to The liquid absorbs heat, and when the water storage device releases heat, the phase change energy storage material changes from liquid to solid to release heat. Choose according to the set temperature of the hot water is 60°C, the phase change energy storage material is paraffin wax of No. 50, and the filling method of paraffin wax is liquid filling. The cylinder body includes a cylinder, an upper cover and a lower bottom.

[0026] Such as figure 1 , The cylinder 12 includes an inner tank 7, a phase-change...

Abstract

A heat-accumulating and heat-insulating water storage device of a solar water heater comprises a barrel body, wherein a phase-change energy storage material is arranged in a heat-accumulating and heat-insulating layer of the barrel body; when the heat-accumulating and heat-insulating water storage device absorbs heat, the phase-change energy storage material changes from a solid state to a liquid state for absorbing heat; when the heat-accumulating and heat-insulating water storage device releases heat, the phase-change energy storage material changes from a liquid state to a solid state for releasing heat; the phase-change energy storage material can be 40-60# paraffin, the specific paraffin grade is selected according to the set temperature of hot water, and the filling way of the paraffin is liquid filling. The heat-accumulating and heat-insulating water storage device can reduce outward heat dissipation of a water storage tank, and greatly improves the heat-insulating effect of the water storage tank; the high-efficiency heat-insulating water tank provided by the invention can retain the temperature drop of water in the water tank to 5 DEG C or below after the night time.

Description

technical field [0001] The invention relates to the application field of heat storage equipment, in particular to a heat storage heat preservation water storage device for a solar water heater. Background technique [0002] Solar water heaters have become a common commodity in people's home life, and are more and more favored by consumers because of their safety, energy saving and environmental protection. The heat preservation of the traditional solar water heater storage tank is to fill a thick layer of polyurethane material between the inner tank and the outer shell, and use the poor thermal conductivity of the polyurethane material to block the outward transfer of heat; there are also products in the polyurethane material and outer shell, A layer of heat reflective film is pasted between the inner tanks to reduce heat dissipation. Due to the poor heat insulation effect of polyurethane materials, low heat storage capacity, and the inability to provide heat to the water s...
